Dodge bulletin 18-063-26
Dodge filed this with NHTSA as a service bulletin dated Jun 25, 2026, received Jul 2, 2026, about the engine. It names 1 model year (2019). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

Common questions
Source: NHTSA, 49 CFR 579.5Is Dodge 18-063-26 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the 18-063-26 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does 18-063-26 cover?
The manufacturer filed it against 1 model year: 2019 Dodge Journey. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
